Summary

This open-label, dose-finding, multi-center study is designed to determine the safety and the maximum tolerated dose of AMG 706 given once daily in combination with either weekly paclitaxel (Arm A) or once-every-3 week docetaxel (Arm B) in subjects with locally recurrent or metastatic breast cancer. Secondarily, this study will evaluate the pharmacokinetic (PK) profile of AMG 706 in both treatment arms, the PK profile of paclitaxel in Arm A and the PK profile of docetaxel in Arm B. Additionally, this study will assess objective tumor response and duration of response. Exploratory endpoints include the investigation of potential biomarker development and to assess the effects of genetic variation in drug metabolism genes, cancer genes and drug target genes on subject response to AMG 706 in combination with paclitaxel or docetaxel.

Conditions

• Locally Recurrent and Metastatic Breast Cancer

Interventions

Type	Name	Description
DRUG	Docetaxel	Subjects assigned to Arm B, cohorts will receive 75 or 100 mg/m2 of docetaxel (based on cohort assignment) on Day 1 repeated every 21 days (1 cycle). AMG 706 will be administered concurrently on Days 3-21 of Cycle 1, and Days 1-21 of Cycle 2 and beyond.
DRUG	Paclitaxel	Subjects assigned to Arm A will receive 90 mg/m2 of paclitaxel on Days 1, 8 and 15 repeated every 28 days (1 cycle). On Arm A, AMG 706 will be concurrently administered on Days 3-28 of Cycle 1, and Days 1-28 of Cycle 2 and beyond.
DRUG	AMG 706	Subjects assigned to Arm A will receive AMG 706 at 50, 75, 100 or 125 mg daily (based on cohort assignment) on Days 3-28 of Cycle 1, and Days 1-28 of Cycle 2 and beyond in combination wth paclitaxel 90 mg/m2. Paclitaxel will be administered on Days 1, 8 and 15 every 28 days. Subjects assigned to Arm B will receive AMG 706 at 50, 75, 100 or 125 mg daily(based on cohort assignment) on Days 3-21 of Cycle 1, and Days 1-21 of Cycle 2 and beyond in combination with docetaxel. Docetaxel will be administered at either 75 mg/m2 or 100 mg/m2 on Day 1 every 21 days.
